An inbound only DNS forwarding rule would be pointless. All DNS queries should be originating from within the network.

EDIT

I think I see what you’re getting at. Assuming that the firewall is running on the NAS vs on the router.

The OP doesn’t specify, but I would assume the firewall rule would be on the router, as that makes the most sense to force all DNS requests on the network to go through the pihole.

I agree.

So the solution, OP, is to set the DNS settings on your NAS to your router’s internal IP so the firewall can redirect the traffic to your new port.

The power to make laws, like codifying Roe vs Wade, lies with congress.

I’m peeved about the SC ruling too, but they didn’t unilaterally hand over all governmental power to the executive.

Because the president had unilateral authority to make laws, right?

Nevermind Mitch McConnell standing up in the senate and saying they’d refuse to cooperate with Obama, it’s Obama’s fault.
